Lot of people grow grocery story miniature roses in their gardens. I've read that they can get to be quite large and that only the flowers are miniature. Of course I'm in 4B so they wouldn't grow as large as they would for others, but I am wondering what others have experienced, especially in the cooler zones. Mine only seem to grow to about a foot tall and don't really flower as much as I'd expect. They've been in the ground for about 4 years already.
